Product Description
Use
For explosive gases and vapours please refer to the ATEX
Supplement for additional safety information on operation in
hazardous zones.
The vacuum pump may only be used as contractually agreed with
Busch. The conveyed medium, the operating liquid and the
temperature ranges thereof may not be changed without written
consent of Busch.
Maximum allowed temperatures:
gas dry: 120 °C
gas saturated: 100 °C
operating liquid: 80 °C
The vacuum pump is thermally suitable for continuous operation
(100% duty).
Principle of Operation
The vacuum pump works on the liquid ring principle.
At standstill, the pump housing (g) shall be filled with an operating
liquid (usually water) to approximately the shaft centreline. On
starting the vacuum pump, the impeller throws the liquid to the
periphery of the housing, where it forms a liquid ring that rotates in
the pump housing. This liquid ring seals the space between the
impeller (h) and the housing (g). In the 12 o’clock position the liquid
ring touches the hub of the impeller (h). As the impeller rotates
clockwise (view from drive end), the liquid ring moves away from
the hub making space for gas to be drawn in through the suction
port (e) (approximately from the 1 o’clock to the 4 o’clock position).
The chamber surrounded by the hub, the liquid ring and two
adjacent impeller blades achieves its maximum volume in the 6
o’clock position. As the impeller continues to rotate, the liquid ring
moves closer to the impeller hub, the volume of the chamber
decreases and the enclosed gas is expelled through the discharge
port (f) (approximately from the 9 o’clock position to the 12 o’clock
position). This sequence is repeated for every chamber between
two impeller blades with each revolution.
The operating liquid also absorbs the heat of compression and
condensation (when conveying saturated media).
The control of the level and the temperature of the operating liquid
are essential for the satisfactory operation of the vacuum pump.
The chapter Installation Prerequisites (➔page 5) gives advice and
explains typical installation options.
In order to achieve a better ultimate/differential pressure, two
stages (both working on the principle described above) are installed
in-line.
Cooling
The vacuum pump is cooled by

•Attach the lifting gear to a crane hook with safety latch
•Adjust slings to give a level lift
•When lifting pump with motor ensure sling is wrapped 1 turn
around motor behind terminal box as shown.
•Lift the vacuum pump with a crane
In case the vacuum pump was bolted to a pallet or a base plate:
♦Remove the stud bolts from the rubber feet
Storage
Short-term Storage
•Make sure that the suction connection and the gas discharge
are closed (leave the provided plugs in)
•Store the vacuum pump
If possible in original packaging,
indoors,
dry,
dust free and
vibration free.
Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere,
frequent temperature changes) conserve the vacuum pump
immediately. In case of favourable ambient conditions conserve the
vacuum pump if a storage of more than 3 months is scheduled.
•Make sure that all ports are firmly closed; seal all ports that are
not sealed with PTFE-tape, gaskets or o-rings with adhesive
tape
Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in
molecular thickness on the packed good and by its electro-chemical
properties effectively suppresses corrosion on metallic surfaces.
However, VCI-products may attack the surfaces of plastics and
elastomers. Seek advice from your local packaging dealer! Busch
uses CORTEC VCI 126 R film for the overseas packaging of large
equipment.
•Wrap the vacuum pump in VCI film
•Store the vacuum pump
If possible in original packaging,
indoors,
dry,
dust free and
vibration free.
Note: For long-term storage (over 6 months) the pump shaft
should be rotated by hand weekly to prevent bearing and/or
shaft indentation problems. Failure to carry out this procedure
could invalidate the product warranty.
For commissioning after conservation:
•Make sure that all remains of adhesive tape are removed from
the ports
•Commission the vacuum pump as described in the chapter
Installation and Commissioning (➔page 5)
Installation and
Commissioning
Installation prerequisites
•Make sure that the integration of the vacuum pump is carried
out such that the essential safety requirements of the Machine
Directive 2006/42/EC are complied with (in the responsibility of
the designer of the machinery into which the vacuum pump is
to be incorporated; (➔page 17: note in the EC-Declaration of
Conformity)
Ancillary Conditions
The chapter Principle of Operation (➔page 3) describes the basic
function of a vacuum pump. This description assumes that the liquid
ring stays liquid all the time.
The condition of both the operating liquid and the conveyed media
depend on the physical conditions pressure and temperature.
At very low pressures and sufficiently high temperatures the
operating liquid can locally transfer into the vapour phase, creating
bubbles within the operating liquid. As the pressure rises towards
the outlet port (e) the bubbles collapse. This process is called
cavitation. In case of bubbles that have been located on surfaces the
operating liquid cannot intrude the cavity left by the bubble equally
from all directions. Instead the inflowing liquid hits the surface with
high speed. This causes erosion, which can destroy the vacuum
pump rapidly. Also the formation of bubbles deteriorates the pump
performance. Cavitation is clearly audible by its crackling noise.
For a trouble-free operation the vacuum pump shall be filled with
operating liquid approximately up to the shaft centre before the
pump is switched on. A low liquid level deteriorates the pump
performance. A dry start causes failure of the mechanical seal on
the shaft of the vacuum pump. A start with a completely flooded
housing damages the blades of the impeller and potentially the
shaft.
Once the vacuum pump is running operating liquid can be supplied.
Excess operating liquid will then be thrown out through the outlet.
The pressure of the supplied operating liquid shall not exceed the
outlet pressure of the vacuum pump by more than 0.1 bar, otherwise
the pump performance will deteriorate. The best solution is a
reservoir under atmospheric pressure from which the vacuum pump
sucks in operating liquid automatically.
CAUTION
In case of non-compliance with the installation prerequisites,
particularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and
adjoining plant components!
Risk of injury!
The installation prerequisites must be complied with.

LM 0100-0800 A, LT 0130-0750 A
page 6 0870700034 / 171101
The pressure control and the operating liquid supply system of a
vacuum pump must therefore fulfil the following tasks:
limit the operating pressure to a value at which no cavitation
will occur
control the level in the operating liquid separator and if
appropriate, cool the operating liquid to a temperature at which
no cavitation will occur
Operating the vacuum pump close to its ultimate pressure requires
large quantities of cool operating liquid. In order to avoid cavitation it
is usually more prudent to limit the minimum working pressure.
The pressure on the suction side of the vacuum pump must not fall
below the minimum allowed operating pressure. Therefore it is not
recommended to use an actuated pressure control valve directly in
the suction line, as the actuator would throttle or potentially even
close the suction line.
The most effective measure to limit the inlet pressure is the use of a
vacuum relief valve.
The vacuum relief valve can either be installed in the suction line or
on the housing of the vacuum pump. The gas supply line of the
vacuum relief valve is usually connected to the liquid separator.
Alternatively ambient air can be used to limit the vacuum.
Feeding ambient air helps to cool the process gas and acts against
condensation or dissolving of process gases into the sealing liquid
and therefore reduces the risk of cavitation. However, it mixes the
process gas with ambient air, i.e. with oxygen, which is possibly not
desired. Drawing gas from the liquid separator avoids mixing with
ambient air. However, this gas is usually warmer, which promotes
the accumulation of condensed or solved process gas in the
operating liquid, hence increasing the risk of cavitation. If the primary
task is to suck vapours, a non-condensing gas should be used.
Layout Proposals
The working principle of the liquid ring is dependent upon a
continuous supply of clean operating liquid, which is normally
water. The operating liquid enters the Vacuum
pump/Compressor/Vacuum and pressure pump through a
connection J on the housing and is discharged from the Vacuum
pump/Compressor/Vacuum and pressure pump along with the
process gas.
For the layout of an operating fluid supply system, there are
basically three different models:
once through cooling / no recovery
partial recovery (open circuit)
total recovery (closed circuit)
All of these arrangements have four basic elements:
Source of the operating liquid (from the water main or reservoir)
Regulating device to control flow of liquid
Means of stopping the flow when the Vacuum
pump/Compressor/Vacuum and pressure pump is shut off
(manual or with solenoid valve)
Means of separating the gas-liquid exhaust mixture to prevent
the build-up of unnecessary back-pressure

Once Through Operation / No
Recovery
The operating liquid is taken directly from a main supply to the
vacuum pump. The operating liquid is separated from the gas and
transferred to a drain as waste. No recirculation or recovery takes
place. This arrangement can be used where operating liquid
conservation or contamination is not a concern. An automatic
solenoid valve can provide for flow of operating liquid simultaneously
with vacuum pump operation (i.e. upon the motor stopping, the valve
closes preventing the housing to be filled with too much operating
liquid). With a manual operating liquid shut off valve, it is important to
open the valve immediately after starting the motor and to close the
valve immediately before switching the motor off.
Version with lateral liquid separator:
Circuit diagram:
Alternative tank with float valve:
After initially priming the pump to the shaft centre line level, the
vacuum pump will draw in the operating liquid from a tank.
This system is suitable for pumps continually operating with suction
pressures below 700 mbar.
With the vacuum pump operating at normal duty, the regulating valve
can be adjusted to achieve optimum vacuum.
Alternative tank with float valve:
Partial Recovery (open circuit)
The operating liquid enters and leaves the vacuum pump in the
same manner as with the once through arrangement. A portion of
the operating liquid is recirculated from the separator tank to the
vacuum pump. The remainder is discharged from the separator and
transferred to the drain as waste. The fresh liquid F is introduced in
sufficient quantity to maintain proper temperature essential for good
vacuum pump performance. This type of arrangement is used where
seal liquid conservation is possible, the consumption can be reduced
by up to 50% depending upon the fluid vapour pressure and
temperature.
The operating liquid level in the separator/recirculation tank should
be at, or slightly below, the centreline of the pump shaft. Provisions
may also be made for high level overflow. This will help prevent
starting the vacuum pump with the housing full of water, which could
overload the vacuum pump and the drive motor.
Version with lateral liquid separator:
Circuit diagram:
Alternative thermostatically controlled operating liquid temperature:
Total Recovery (closed circuit)
This arrangement is for total recirculation of the operating liquid. A
heat exchanger is added to remove the heat of compression, friction
and condensation from the operating liquid before it is reintroduced
back into the vacuum pump. For prolonged operation at suction
pressure above 300 hPa abs (300 mbar abs) a circulating pump is
normally installed and mandatory at suction pressure above 400 hPa
abs (400 mbar abs) or when suction pressure varies during cycling
operations.
The operating liquid level in the separator/recirculation tank should
be at, or slightly below, the centreline of the pump shaft. Provisions
may also be made for high level overflow and low level make-up.

LM 0100-0800 A, LT 0130-0750 A
page 8 0870700034 / 171101
This will help prevent starting the vacuum pump with the housing full
of water, which could overload the vacuum pump and the drive
motor.
The heat exchanger (W) must be capable of removing approx. 85%
of the drive power and any possible condensation heat.

Mounting Position and Space
•Make sure that the following ambient conditions will be
complied with:
ambient temperature: 0 … 40 °C
ambient pressure: atmospheric
•Make sure that the environmental conditions comply with the
protection class of the drive motor (according to the nameplate)
•Make sure that the vacuum pump will be placed or mounted
horizontally
•Make sure that the base for placement / mounting base is even
•Make sure that in order to warrant a sufficient cooling there will
be a clearance of minimum 1 m between the vacuum pump
and nearby walls
•Make sure that no heat sensitive parts (plastics, wood,
cardboard, paper, electronics) will touch the surface of the
vacuum pump
•Make sure that the installation space or location is vented such
that a sufficient cooling of the vacuum pump is warranted
•Make sure that the vacuum pump will not be touched
inadvertently during operation, provide a guard if appropriate
Suction Connection
In case the inlet gas can contain dust or other foreign solid particles:
♦Make sure that a suitable filter (5 micron or less) is
installed upstream of the vacuum pump
•Make sure that the suction line fits to the suction connection (a)
of the vacuum pump
In case the length of the suction line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload
of the vacuum pump. Seek advice from your Busch representative!
In case the vacuum pump shall be maintained after shutdown of the
vacuum pump:
♦Provide a manual or automatic operated valve (= non-
return valve) in the suction line
•Make sure that the suction line does not contain foreign
objects, e.g. welding scales
Gas Discharge
The discharge piping should not exceed an elevation of more
than 600 mm above the discharge flange (c) of the pump
housing until the liquid is separated. Too high an elevation will
cause back pressure and possible drive motor overload.
The discharged gas must flow without obstruction. It is not
permitted to shut off or throttle the discharge line or to use it as
a pressurised air source.
•Make sure that the discharge line fits to the gas discharge (k) of
the vacuum pump
•Make sure that the line size of the discharge line over the entire
length is at least 2”
In case the length of the discharge line exceeds 2 m it is prudent to
use larger line sizes in order to avoid a loss of efficiency and an
overload of the vacuum pump. Seek advice from your Busch
representative!
•Make sure that the discharge line either slopes away from the
vacuum pump or provide a liquid separator or a drip leg with a
drain cock, so that no liquids can back up into the vacuum
pump
Electrical Connection / Controls
•Make sure that the stipulations acc. to the EMC-Directive
2004/108/EC and Low-Voltage-Directive 2006/95/EC as well as

Setting Operating Conditions
Selection of Operating Liquid
A continuous flow of operating liquid is required whenever the
vacuum pump is operating. Water is usually used as the operating
liquid for the conveyance of air and other inert gases. Other ring
liquids may be used in order to comply with the selected gases and
separation methods.
The kinematic viscosity at operating temperature shall not exceed
2 mm²/s and higher viscosities require increased drive power. The
vapour pressure of the operating liquid should be at least 16 mbar
below the desired operating pressure (vacuum level) at the pump
suction connection, to avoid risk of cavitation. Higher vapour
pressures deteriorate the suction capacity and the ultimate pressure
as stated in the performance tables or curves. In case of use of
operating liquids other than water, confirmation of the vacuum
pump’s conveying characteristics shall be sought from Busch.
If liquids get conveyed together with the process gas (typically up to
50% of the quantity of the circulating liquid rate as given in the
datasheet) the addition of fresh liquid can be reduced significantly.
Condensation of vapour inside the vacuum pump is normal and
acceptable but in extreme circumstances can cause cavitation and
destroy components of the vacuum pump. Condensation upstream
of the vacuum pump (spray or surface condenser) is an alternative
solution in extreme cases of high vapour load and insufficient inert
gas. Under certain conditions the accumulating condensate can be
conveyed along by the vacuum pump. Otherwise a separate liquid
pump must be provided for. The design shall be performed by the
manufacturer/supplier.
The suction capacity (or volume flow) as given in the performance
table is achieved at an operating water temperature of 15°C.
Operation at higher water temperatures leads to a reduced suction
capacity (or volume flow), but leaves the option to save fresh water
or cooling liquid in case of open or closed circuit cooling. This liquid
rate shall be set by means of the regulating valve rFor rBonly to
such a quantity, that the required suction capacity (or volume flow) is
achieved. The regulating valve shall be locked in this position.
Fresh Water Requirement
Fresh water flow rate requirements are shown in the technical data
section ➔page 24. The data given applies to once through
operation.
These water flow rates result in approximately a 5.5°C rise in
temperature for a single stage vacuum pump, and a 2.7°C rise for a
two stage vacuum pump when handling dry air. Condensable
vapours in the gas stream, however, will add to the heat load and
cause a higher temperature rise through the vacuum pump.
Partial recovery flow rates may be reduced by up to 50% dependent
upon temperature rise through the vacuum pump (see above
comment).
If operating speed is varied from the given values, the flow rate
requirements vary accordingly.
Operating Liquid Level
Note: The options to check the level depend on the installation. In
case the installation provides no means for level check, undo the
plug (b). Excess operating liquid will then flow out of the port. If
necessary fill in operating liquid, until it reaches the bottom edge of
the port. Reinsert the plug (b) prior to starting the vacuum pump.
•Make sure that the operating liquid reaches the middle of the
shaft when the vacuum pump is to be started
Pressure Control
At very low pressures and sufficiently high temperatures the
operating liquid can locally transfer into the vapour phase, creating
bubbles within the operating liquid. As the pressure rises towards
the outlet slot the bubbles collapse. This process is called cavitation.
In case of bubbles that have been located on surfaces the operating
liquid cannot intrude the cavity left by the bubble equally from all
directions. Instead the inflowing liquid hits the surface with high
speed. This causes erosion, which can destroy the vacuum pump
rapidly. The formation of bubbles also deteriorates the pump
performance. Cavitation is clearly audible by its crackling noise.
The working pressure of the vacuum pump shall therefore be
sufficiently above the vapour pressure of the operating liquid. In
particular the pressure control in the vacuum system must by no
means be achieved by throttling or even closing of the suction line!
The vapour pressure of the operating liquid and consequently the
ultimate pressure can be reduced by cooling. However, this
increases the cooling water flow considerably. In most cases the low
ultimate pressure is not required and cavitation shall be avoided by
means of vacuum limitation rather than cooling.
Removing Contaminants and
Deposits
•In closed operating liquid circuits with water use softened water
to prevent scale formation
•For all operating systems make sure that no particles with a
diameter larger than 0.1 mm will intrude the vacuum pump,
neither via the process gas nor via the operating liquid. Filter
out larger particles before the vacuum pump. Use a knock out
pot and/or filter to remove larger particles from the process gas.
Use a strainer or filter to remove larger particles from the
operating liquid.
The particle contamination concentration shall not exceed 5% by volume.
When removal of particles is impractical then a clean alternative operating
liquid source should be used. A continuous flow of operating liquid is required
whenever the vacuum pump is operating.
Impeller Casings Purge:
•The impeller casings have tangential drains which can be piped
away to purge dirt particles in dirty applications. This will
increase the life of the pump but is not a substitute for
preventing foreign matter entering the vacuum pump in the first
place. When casing purge is used additional service liquid flow
should be supplied to allow for the loss through the purge.
CAUTION
Starting the vacuum pump with a completely flooded housing
can bend the blades of the rotor.
When the vacuum pump is started the operating liquid
should only reach the middle of the shaft.
CAUTION
During operation the surface of the vacuum pump may reach
temperatures of more than 70 °C.
Risk of burns!
The vacuum pump shall be protected against contact during
operation, it shall cool down prior to a required contact or heat
protection gloves shall be worn.

Maintenance
•Prior to disconnecting connections make sure that the
connected pipes/lines are vented to atmospheric pressure
Maintenance Schedule
Note: The maintenance intervals depend very much on the
individual operating conditions. The intervals given below shall be
considered as starting values which should be shortened or
extended as appropriate.
Particularly heavy duty operation, such as high dust loads in the
environment or in the process gas, other contaminations or ingress
of process material, can make it necessary to shorten the
maintenance intervals significantly.
Monthly
•Check for audible abnormal noise, e.g.:
Excessive rumble (possible cavitation problem)
Periodic click/knock (possible mechanical contact / bearing
degradation)
Mechanical seal squealing noise (possible lack of lubrication)
•Check for excessive vibration
Vibration should be less than 5.38 mm/s RMS when measured in the
axial, vertical radial and vertical horizontal planes on the bearing
housing. High vibration could indicate a coupling misalignment,
fixing bolt looseness or bearing degradation. Also check for excess
load and service liquid flow.
•Check the operating liquid temperature
(with a hand held probe or a permanent gauge, if fitted; consult
the order documentation for the specified operating liquid
temperature)
•Check the bearing temperature
(with a hand held probe or a permanent gauge, if fitted; at 25°C
ambient temperature the bearing temperature should not
exceed 60°C (operating liquid = water) or 80°C (operating liquid
= oil); for other ambient temperatures adjust accordingly)
•Check that the vacuum pump achieves the usual/specified
vacuum level
•Check all pipe work for leakage
•Check the mechanical seals for leakage. This will be observed
at the tell-tale holes in the bearing housings. Replace seals
and bearings if signs of leakage.
•Make sure that the vacuum pump is shut down and locked
against inadvertent start up
In case of operation in a dusty environment:
♦Clean as described under ‘Every 6 Months’
Every 1000 Operating Hours:
For LM 0800 A, LT 0630 A & LT 0750 A size of pumps ONLY:
•Regrease the bearings (Add 15g of lithium based grease NLGI
class 2 to each bearing).
Smaller LM & LT pumps use bearings which are greased for life
Every 6 Months:
•Make sure that the housing is free from dust and dirt, clean if
necessary
•Make sure that the vacuum pump is shut down and locked
against inadvertent start up
•Clean the fan cowling, the fan, the ventilation grille and the
cooling fins of the motor
Every Year:
•Make sure that the vacuum pump is shut down and locked
against inadvertent start up
In case an inlet screen (715) is installed:
♦Check the inlet screen (715), clean if necessary
•Remove the fan cowling of the drive motor, turn the shaft by
hand and check for ease of rotation (seizure or binding could
indicate ingress of foreign material, misalignment or product
build up)
Version with relubricatable bearings:
♦Check the grease condition of the bearings (e.g. water or
debris contamination)
CAUTION
During operation the surface of the vacuum pump may reach
temperatures of more than 70 °C.
Risk of burns!
DANGER
In case the vacuum pump conveyed gas that was
contaminated with foreign materials which are dangerous
to health, harmful material can reside in filters.
Danger to health during inspection, cleaning or
replacement of filters.
Danger to the environment.
Personal protective equipment must be worn during the
handling of contaminated filters.
Contaminated filters are special waste and must be
disposed of separately in compliance with applicable
